Abstract

A manufacturing method for an electrode material, the manufacturing method including, in a presence of an alkali metal supplying source and a solvent, dynamically pressurizing an amorphous aggregate including at least an active material in a dynamic pressurizer, sending out in a sending direction, and continuously discharging the aggregate in the sending direction from the dynamic pressurizer.

Claims

exact text as granted — not AI-modified
1 - 19 . (canceled) 
     
     
         20 . A manufacturing method for an electrode material, the manufacturing method comprising:
 a depressurizing process of placing a mixed solution including at least an active material in a depressurized state; and   a doping process of doping an alkali metal to the active material.   
     
     
         21 . The manufacturing method according to  claim 20 , wherein
 at least one part of the doping process is carried out with the depressurizing process.   
     
     
         22 . The manufacturing method according to  claim 20 , wherein
 the depressurizing process is carried out before the doping process.   
     
     
         23 . The manufacturing method according to  claim 20 , wherein
 the mixed solution is kneaded, stirred, or mixed in the doping process.   
     
     
         24 . The manufacturing method according to  claim 20 , wherein
 a pressure in the depressurized state is within a range of 0.01 kPa to 0.05 MPa.   
     
     
         25 . The manufacturing method according to  claim 20 , wherein
 the mixed solution is prepared before the depressurizing process.   
     
     
         26 . The manufacturing method according to  claim 20 , wherein
 the active material is a negative electrode active material.   
     
     
         27 . A manufacturing method for an electrode, comprising:
 manufacturing an electrode material the manufacturing method according to  claim 20 , and   manufacturing an electrode using the electrode material.   
     
     
         28 . A manufacturing method for a capacitor comprising a positive electrode, a negative electrode, and an electrolyte, the method comprising performing the manufacturing method according to  claim 27  to obtain the negative electrode of the capacitor. 
     
     
         29 . A manufacturing method for a battery comprising a positive electrode, a negative electrode, and an electrolyte, the method comprising performing the manufacturing method according to  claim 27  to obtain the negative electrode of the battery. 
     
     
         30 - 35 . (canceled) 
     
     
         36 . A manufacturing device for an electrode material, the manufacturing device comprising:
 (A) a container that accommodates a mixed solution including at least an active material and an alkali metal supplying source; and   (B) a depressurizing part that depressurizes an inside of the container.
